Integrated Surface Water and Groundwater Analysis

Dear Colleagues,

Comprehensive understanding of groundwater - surface water (GW–SW) interaction is essential for effective water resources management. Groundwater (GW) and surface water (SW) are closely connected components that are constantly interact each other within the Earth’s hydrologic cycle. Many studies utilized observations to explain the GW-SW interactions by carefully analyzing the behavior of surface water (SW) features (streams, lakes, reser voirs, wetlands, and estuaries) andthe related aquifer environments. Surface water bodies gain water and solutes from groundwater systems, and in other cases surface water bodies recharge groundwater, which causes changes in groundwater quality. The interfaces between GW and SW environments, such as hyporheic - benthic zones and riparian corridors often function as biogeochemical hotspots and can have significant influences on the entire stream ecology. However, unlike visible surface water, groundwater, an invisible water resource, is not easy to measure or quantify directly. Nevertheless, demand for groundwater that is highly resilient to climate change is growing rapidly. Furthermore, groundwater is the prime source for drinking water supply and irrigation, hence critical to global food security. Groundwater needs to be managed wisely, protected,and especially sustainably used. However, this task has become a challenge to many hydrologic systems in arid to even humid regions because of added stress caused by changing environment, climate, land use, population growth, etc. In this issue, the editors invite contributions on various research areas such as the integrated GW-SW analysis, sustainable management of groundwater, and the interaction between GW and SW. Methodologies, strategies, case studies as well as quantitative techniques for dealing with combined surface water and groundwater management are of interest for this issue. Studies describing how groundwater resources benefit from an Integrated Water Resources Management (IWRM) approach are welcome. This Special Issue aims to elevate integrated understanding of the science in GW-SW system through healthy discussions in the GW-SW system researc h community. The editors also welcome contributions from all relevant areas that improves every aspectof GW-SW connections and its beneficial use.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Hydrology is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
